Controlling with built-in sensor
Robots has a so-called ‘force/torque sensor’ integrated in the tool flange. It provides greater precision ad sensitivity, which means that the operator can move the robot around using minimal physical strength.
When using Miga Smart Tool, this force/torque sensor makes it significantly easier to control the robot.
Touch experience
The screen has a great touch experience, which resembles those on mobile phones.
Repeatability
Repeatability measures the robot’s ability to return to the exact positions it was taught with high accuracy.
- 5: ± 0.1 mm
- 10: ± 0.1 mm

So, which robot do you need?
It is no secret that the e-Series has many advantages compared to the CB-Series. The e-Series robots will make programming in any welding production less complicated and easier to carry out.
Consider how the advantages and disadvantages of both series will impact the processes in your welding production. Talk it over with one of our welding specialists or CoWelder experts prior to selecting your CoWelder solution.
What is the CoWelder?
The CoWelder is a collaborative welding robot, designed by Migatronic. We have combined the best and latest welding technology with innovative cobot technology from Universal Robots, creating a new category-defining welding solution with broad applications.
